ADR-0087 exemption (no-migration-prescription): No key of any schema is added, removed, renamed or re-shaped, and no export or type changes: `DatasourceSchema` keeps `external.credentialsRef` authorable, and the doors that make a stored body active refuse one value of it, a reference the row they write into does not hold now. A stored row is never re-judged at rest: it is read and served as before, and only the write that would make it the active row is judged. There is nothing for a migration to rewrite and no tombstone; the remedy is a door, the datasource admin door's `secret`, which the refusal names.
